Fields

mutWeightRate :: Double: How often weights are mutated
newWeightRate :: Double: How often weights are replaced if mutated
pertAmount :: Double: Max amount of perturbation
weightRange :: Double: A new max is between negative this and positive this
addConnRate :: Double: How often new connections are made
addNodeRate :: Double: How often new nodes are added
recurrencies :: Bool: Whether to allow recurrent connections
noCrossover :: Double: Percent of population that mutates without crossover
disableChance :: Double: How likely that a disabled parent results in a disabled child
